The correct Answer is:
To solve the problem step by step, we will denote the two digits of the two-digit number as \( x \) (the tens digit) and \( y \) (the units digit). ### Step 1: Set up the equations based on the problem statement. We know from the problem that: 1. The sum of the digits is 14: \[ x + y = 14 \] 2. The difference between the two digits is 2: \[ x - y = 2 \] ### Step 2: Solve the equations simultaneously. We can solve these two equations together. First, we can add the two equations: \[ (x + y) + (x - y) = 14 + 2 \] This simplifies to: \[ 2x = 16 \] Now, divide both sides by 2: \[ x = 8 \] ### Step 3: Substitute the value of \( x \) back into one of the equations to find \( y \). Now that we have \( x \), we can substitute it back into the first equation: \[ 8 + y = 14 \] Subtract 8 from both sides: \[ y = 14 - 8 = 6 \] ### Step 4: Calculate the product of the two digits. Now that we have both digits, \( x = 8 \) and \( y = 6 \), we can find the product: \[ x \cdot y = 8 \cdot 6 = 48 \] ### Final Answer: The product of the two digits of the two-digit number is \( 48 \). ---
